Title: Improved method of treating superphosphate
IPC: C05B19/02
Filed: 1941-01-01
Abstract: 551,360. Granulating superphosphate. PHOSPHATE CO-OPERATE CO. OF AUSTRALIA, Ltd. Jan. 1, 1941, No. 20. Convention date, Dec. 20, 1939. [Class 1 (iii)] [Also in Group V] Superphosphate, or fertiliser containing superphosphate, is brought to a plastic consistency by wetting or by the addition of fine superphosphate, and is passed between two high speed rolls or other equivalent mechanical contrivances moving at a peripheral speed of more than 750 feet per minute, wherein it is compressed and whence it is projected into and falls through a non-injurious gaseous medium, e.g. air. The size of the particles thus formed may be varied by adjustment of the rolls and regulation of the plasticity. The preferred peripheral speed is 4,000 feet per minute, the outward projection of most of the particles being about 30 feet. The particles may fall 60 feet through air, this fall assisting the drying and cooling of the particles. The two rolls may rotate at different speeds.

Title: Improvements in feed water supply apparatus
IPC: F22D5/10
Filed: 1931-01-01
Abstract: 368,442. Feedwater supply systems for steam boilers. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Ingersoll- Rand Co. ; 15, Exchange Place, Jersey City, New Jersey, U.S.A.) Jan. 1, 1931, No. 50. [Classes 64 (i) and 123 (ii).] In a feedwater supply system in which the condensate from a condenser A is circulated by a pump G and pipe H to heaters J, K, which may be supplied with steam from separate sources and from which the drip is returned by a drip pump e and pipe f to the heaters, connections g, 23 are provided so that under low load conditions the pump e can also remove condensate from the condenser A, the pump G being stopped. During normal operation a check valve h in the pipe g is kept closed by an excess pressure on the drip pump side of the valve ; this pressure is maintained by a control valve j operated by float mechanism v in the drip chamber Q. Check valves x, y are provided on the discharge side of the pumps G, e. A suitable pressure on the outlet of the pump G is maintained by a valve 4 actuated by pressure fluid supplied from a pipe 21 through a piston valve 19 to a pipe 20. The valve 19 is actuated by a float 15 in the hot-well C. A valve 4<1> on the pipe 23 is also controlled by the pressure fluid ; its spring is weaker than that of the valve 4, so that normally valve 4<1> is closed while valve 4 is open. Under low load conditions the pump G is stopped ; the level in the hot-well C rises causing the float 15 to actuate the valve 19 so that first the pressure fluid is cut off and then the pipe 20 is placed in communication with the atmosphere through the pipe 22, so that both valves 4, 4<1> open fully. The pump e now discharges through both pipes f, 23, causing a fall in pressure on the check valve h which allows it to open so that condensate flows through the pipe g.

Title: Disabling devices impact actuator
IPC: F42B3/00
Filed: 1974-01-02
Abstract: 1446095 Thermo-aluminic processes BUCK KG 2 Jan 1974 [2 Jan 1973] 00066/74 Heading B3V Gun barrels &c. are disabled by a device coinprising a casing containing a charge of thermic mixture within a space defined at least partially by a heat-degradable casing wall part of low thermal conductivity, the degradation time of the wall part being substantially equal to or not much greater than the reaction time of the thermic mixture. Thus, since preservation of the casing and separation of iron and slag is unnecessary, the casing may be carbonized or destroyed after the reaction time which may be reduced for commercial mixtures by appropriate selection of the mixture ratios or grain size or by addition of accelerators. Reaction time may also be reduced by compressing the mixture in the casing, e.g. within a lining of graphite paper. As shown, the device has a friction igniter 16, a transmission composition 17 and an ignition composition 18 within the alumino-thermic charge 11. The casing consists of layers of agglutinated paper impregnated with sodium silicate. Alternatively, it can be formed of asbestos paper; layers of the casing may be of different materials.

Title: Manufacture of epoxy compounds and araliphatic compounds
Inventor: KOLLAR JOHN
IPC: C07C5/373
Filed: 1965-01-01
Abstract: Alkenylaromatic and alkylaromatic hydrocarbons are made by dehydration or hydrogenation, respectively, of aralkyl alcohols obtained as by-products in the epoxidation of olefinic compounds using aralkyl hydroperoxides. Prefered aralkyl hydroperoxides are those derived from alkylaromatic compounds having at least one hydrogen atom on the carbon adjacent to the aromatic ring; reduction to the corresponding aralkyl alcohol and subsequent dehydration yields styrene type hydrocarbons, the preferred hydroperoxides of ethylbenzene and cumene yielding styrene and a -methylstyrene. Dehydration may be effected in the vapour phase at 180-280 DEG  C. over a dehydration catalyst, e.g. silica, alumina or, particularly, titania.  Hydrogenation of the aralkyl alcohol to the corresponding alkylaromatic hydrocarbon is carried out in a known manner.ALSO:Olefinically unsaturated compounds are epoxidized by reaction in the liquid phase with an aralkyl hydroperoxide in the presence of a metal epoxidation catalyst which contains at least one metal other than alkali metals or alkaline earth metals.  The epoxidation proceeds with reduction of the hydroperoxide to the corresponding aralkyl alcohol which is subsequently dehydrated or hydrogenated to the corresponding aralkenyl or aralkyl compounds (see Division C5).  Specified unsaturated compounds include C2- 30 aliphatic and alicyclic olefins, esters, alcohols, ketones, ethers, mercaptans and alkenyl chlorides. Preferred hydroperoxides are those derived from alkyl-aromatic compounds having at least one hydrogen atom on a carbon adjacent to the ring, particularly cumene and ethylbenzene. Specified catalysts are those containing compounds of Mo, W or V.  It is preferred to add the catalyst in the form of a compound which is at least partially soluble in the reaction medium, e.g. as a carboxylate or carbonyl. The epoxidation may be effected at -20 DEG  to +200 DEG  C., preferably in the presence of a solvent. Examples describe the epoxidation of propylene, 4-vinyl cyclohexene, octene-1, dodecene-1 or hexadecene-1.

Abstract: 1,086,094. Continuous casting. UNITED STEEL COMPANIES Ltd. Nov. 19, 1965 [Nov. 24, 1964], No. 47823/64. Heading B3F. In a method of continuous casting in which the molten metal is poured from a tundish 1 into a reciprocating mould 4 means are provided for connecting the tundish to the mould so as to form a chamber through which the molten metal passes and which contains a reducing or an inert gas. The chamber comprises a cooled upper part 13 attached to the tundish and lower part 15 which is attached to the mould and an intermediate part which effects sealing engagement between the ports 13 and 15. The seals 20 permit the axial reciprocation of the mould and the seal 21 permits adjustment of the port 13 transversely of the mould. Prior to the pouring of the metal reducing or inert gas is introduced into the chamber through passage 24 to purge the mould and chamber and is subsequently supplied during the casting operation. The gas pressure during casting is maintained substantially atmospheric by controlling the gas supply through passage 24 and the escape through passage 25 in conjunction with the level of metal in the mould. The choice of gas used in the process depends on the nature of the material being east and include propane, butane, nitrogen etc. or suitable combinations of such gases and whereby oxygen concentration in the chamber is not greater than 250 parts per million. In a further embodiment. Fig. 6 (not shown) part spherical seaitings are provided on the upper and lower ports of the chamber member to facilitate slight angular misalignment of the tundish and the mould for example by tilting of the tundish or by reciprocation of the mould in an arcuate path, when a curved mould is used.

Abstract: 1,124,061. Photo-electric communication apparatus. PLESSEY-U.K. Ltd. Jan. 31, 1966 [Feb. 4, 1965], No.4891/65. Heading G1A. [Also in Division G2] A communications apparatus includes sighting means (e.g. binoculars) having an optical system with associated selective radiation diverting means which extracts from or injects into the visible light beam received or transmitted by the optical system, non-visible intelligence, by providing a secondary focus at which intelligence receiving means or transmitting means may be located. A communications link may thus be provided between two operators viewing each other over a large distance through binoculars provided with transmitter and receiver means. In a prismatic binocular system, Fig. 1, the selective radiation diverting means is a dichroic coating 5 on the surface of the first prism which reflects any infrared radiation entering the system to a focus at 6, where an infrared detect- or may be located. Visible light passes through the system and can be viewed. An optical system including a receiver such as this, could form one side of the pair of binoculars, while the other side could be an optical system with a gallium arsenide lamp at position 6 to act as a transmitter of infrared light. In an alternative arrangement to enable the secondary focus to be provided outside the visible light path an inclined dichroic mirror (8), Fig. 2 (not shown) and, perhaps, further mirrors, are used. The invention is applicable to Galilean binoculars also, Fig. 3 (not shown). The gallium arsenide lamp may be modulated with a speech signal from a microphone and detected signals applied to headphones.

[Classes 37 and 53] [Also in Groups XXII and XXXVIII] The amount of heat passing through a wall, such as that of a boiler, is measured by cementing to the wall a disc, comprising a sheet of commercial tellurium 1, coated on both sides 2, 3 with a material such as copper or silver having a high thermo-electric power compared with the tellurium, and connecting the two coatings to a galvanometer 4. Two thermojunctions are thus formed the net EMF of which gives the difference in temperature between the two sides of the disc and thus the amount of heat flowing. The copper is rhodium-plated to prevent copper telluride being formed. Constantan or other materials, of which nickel and silicon are mentioned in the Provisional Specification, may be used instead of tellurium if high sensitivity is not required. In a modification, a disc is used comprising a sheet of electrically insulating material coated on both sides with material, such as semi-conductors having high temperature coefficients of resistance and the difference of temperature of the two coatings measured by a differential arrangement.
